One approach to keeping your Google Drive backups (more) secure in the event your web site is hacked:

1. Share the UpdraftPlus folder with a second Google account. View access is fine. If you want to remove the source files after copying to the second account, grant edit access.
2. On your second Google account, create an unshared folder (e.g. UpdraftPlusCopy).
3. On your second Google account, go to script.google.com. Copy/paste the following (I renamed myFunction to CopyNewFiles) and replace the [bogus] folder IDs with the folder IDs for your source/destination folders:
   function CopyNewFiles() {
   var SourceFolder = DriveApp.getFolderById(‘JMtgsgM9sY9Fe5Z7wCbb4YVVqfeZiZ’);
   var SourceFiles = DriveApp.getFolderById(‘JMtgsgM9sY9Fe5Z7wCbb4YVVqfeZiZ’).getFiles();
   var DestFolder = DriveApp.getFolderById(‘SFGXwgvX6DmkAvPrrnWC2KY3imy7s2’);
   var DestFiles = DriveApp.getFolderById(‘SFGXwgvX6DmkAvPrrnWC2KY3imy7s2’).getFiles();
   var NotInDest = true;
   while (SourceFiles.hasNext()) {
   SourceFile = SourceFiles.next();
   while (DestFiles.hasNext()) {
   DestFile = DestFiles.next();
   if (SourceFile.getName() === DestFile.getName()) {
   NotInDest = false;
   }
   }
   if (NotInDest) {
   SourceFile.makeCopy(SourceFile.getName(), DestFolder);
   NotInDest = true;
   }
   DestFiles = DriveApp.getFolderById(‘SFGXwgvX6DmkAvPrrnWC2KY3imy7s2’).getFiles();
   }
   }
4. Optionally, rename the project. Save it (Ctrl+S) works and click the Run button.
   The first time you run it, you should be prompted to grant the script access to manage your (second Google account) Drive.

The script above will copy all files from SourceFolder to DestFolder that don’t already exist (identically-named file) exist in the DestFolder. If you are concerned about storage limits/cost, you could update the script to remove the original file after copying (example below). With that approach, you can remove/comment the code that checks for identically-named files in DestFolder, since that should never be the case if you remove the original file in SourceFolder. To do a restore from the UpdraftPlus plugin, you would need to copy/move the backup files back to the UpdraftPlus folder on the first Google account.

function CopyNewFiles() {
var SourceFolder = DriveApp.getFolderById(‘JMtgsgM9sY9Fe5Z7wCbb4YVVqfeZiZ’);
var SourceFiles = DriveApp.getFolderById(‘JMtgsgM9sY9Fe5Z7wCbb4YVVqfeZiZ’).getFiles();
var DestFolder = DriveApp.getFolderById(‘SFGXwgvX6DmkAvPrrnWC2KY3imy7s2’);
while (SourceFiles.hasNext()) {
SourceFile = SourceFiles.next();
SourceFile.makeCopy(SourceFile.getName(), DestFolder);
SourceFolder.removeFile(SourceFile);
}
}
